The article is devoted to the management of an oil well with an electric submersible pump (ESP) according to the schedule of prescribed productivity under the action of limiting factors. The urgency of the task is dictated by the necessity of fulfilling indicators of planned performance considering short-term programs to compensate for shortfalls or quotas submitted by the higher-level commands. The implementation of such solutions on the information resources of shop automation is possible using industrial Internet technologies that ensure remote modes of operational control in real time. The purpose of the article is to synthesize the program regulator based on solving inverse problems with reference to the original equations of the barometric model of an oil well with an ESP of the second-order. The article formalized the original task of program regulation, presents the basic assumptions and structure of a three-channel regulator that stabilizes the target production rate in compliance with following functionality limitations on the gas factor and the dynamic level above the pump intake. The results of computational experiments of a program regulator performance for identifying dynamics of reservoir conditions drifting demonstrate the validity of the solution under consideration for a well with ESP, determining the system principles of expansion for taking into account additional constraints.
